Application led October 8, 1913. Serial No. 794,018.

To all whom t may concern.'

Be it known that 1, CHARLES KELLEY, a citizen of the United States, residing at Bellair, in the county of Crawford and State of Illinois, have invented certain new and useful Improvements in Cooling Ap- .paratus for Gas-Engines, of which the following is a specilication.

My invention relates to new and useful improvements in cooling apparatus for gas engines, and more particularly to that class of gas engine coolers adapted to be installed in connection with stationary gas engines.

The object of this vide a gas engine cooler of the type described which shall obviate the necessity of the use of a pump to circulate the cooling water.

A further object of this-invention is to provide a gas engine which may be easily installed and which' shall be inexpensive to manufacture, operate and maintain.

A still further object of this invention is tov provide a gas engine cooler which shall provide for effective circulation ofgthe cooling water throughout the water jacket of the engine at all times when the engine is in operation. f

With these and other objects in View this invention consists in the peculiar' combination and construction of the various partsof a gas engine cooler as hereinafter describe and more particularly set forth in the appended claims.

eferring to the drawings wherein similar reference numerals indicate similar parts wherever used, Figure 1 is a vertical side elevation, partly broken away, showing a gas engine equipped with the improved engine cooler; Fig. 2 is a detail section of one of the valves controlling the flow of water; Fig. 3 is a detail sectional view of another of the valves controlling the water.

he numeral 4 designates a gas engine 'of any improved type. having the usual cylin-Y der 6 provided with a water jacket 7, mix? ing chamber 8 containing the ordinary valve 9, operated in the usual manner. Located at any suitable distance from the gas engine is provided a tank 10 adapted to be filled with water or any suitable cooling liquid, and having attached thereto at its lower portion. a pipe 11 having thereon an L 12 carrying a Hap valve 13 and an extension 14, said invention is to pro- Y extension 14 being in open connection with the under cylinder portion of the water jacket 7. j

Connected to the mixing chamber 8 by means of an l.. 15 is a vertical pipe 16, provided with a hand valve 17, and having an angular pipe 18 fastened thereto by means of an L 19, said angular pipe 18 being' in turn connected by means of an l.. 20 to a re ducer 21 having in connection therewith a pipe 22 of larger diameter than the pipes 11, 16 or 18, said pipe carrying a liap valve 22 which is opened by suction in the chamber 8 and' closed when Said suction ceases. rlhe pipe 22 in turn carries a 'la 23, having a reducer end 24 connected to a pipe 25 which communicates with the upper cylinder portion of the water jacket 7. Attached to the T 23 is a pipe 26, carrying a flap valve 27 and also a l' 28, having attached thereto a verticall pipe 29 open tothe air. Adjacent the T 26 is a long section of pipe 30 which extends over the water tank 10 and discharges into the saine by means of an an le nozzle 31.

he operation of my device is as follows: Upon the intake stroke of the engine 4 a suction is formedin the mixing chamber 8, which suction in turn is transmitted through the pipes 1G, 18 and 22, and by means of the pipe 25 serves to lift a column of water upwardly into the pipe 22 from the water chamber 7. rl`his suction causes the valve 27 to remain in closed position, and also serves to open the valve 13 which allows water from the tank 10 to pass through the pipes 11 and 14 upwardly into the under cylinder portion of the water jacket 7. |The pipe 22 vbeing of .larger diameter than the rest of the pipes the column of water therein is so heavy that the suction does not lift the said column much higher than the T 23. The intake stroke having been completed the suction within the chamber 8 and pipes 16,18, 22 and 25 ceases. The valve 13 closes and the column of water within the pipe 22 no longer' h eld in a vertical'position by means of the suction falls back downwardly and out through .the pipe 26, opening the valve 27, thence through the ,pipe 3f) and the nozzle 3l into the tanklO.

The fresh charge of water which has come into the cylinder jacket by means of the pipe 14 fills the water jacket and prevents the reside of the cylinder and allowedto flow diturn thereto of `the column of water within rectly into the cylinder at the other side. 3o
